SHIFT OF BAND GAP FROM DIRECT TO INDIRECT AND OPTICAL RESPONSE OF LiF UNDER PRESSURE
Original language description
We hereby are reporting the transition pressure at which lithium fluoride (LiF) compound transforms from direct band gap to indirect band gap insulator on the basis of FP-LAPW calculations. The fundamental band gap of LiF compound suffers direct to indirect transition at a pressure of 70 GPa. The study of the pressure effect on the optical properties e. g. dielectric function, reflectivity, refractive index and optical conductivity of LiF in the pressure between 0-100 GPa, shows that this pressure rangeis very critical for LiF compound as there are significant changes in the optical properties of this compound.
